Vite bundles development build of react-dom in production

Describe the bug

I have scaffolded a project using create-vite-app with the react-ts template for an app which also uses material-ui and firebase. I ran yarn build and everything seemed to go fine. I also added rollup-plugin-visualizer to see what has been packed into the JS. When I saw the report, the development build of react-dom (aka @pika/react-dom/source.development.js) was bundled in the file. The file is massive, and takes half of my production build. Here is a screenshot from the visualizer:

I also tried a transform from vite.config.ts but no avail.

Reproduction

There is not a need of reproduction as this anomaly seems to be vite-agnostic. This behaviour will also happen on fresh react-ts builds.

Have a look: https://vitejs.dev/config/#resolve-alias You’ll need to refactor alias object to resolve.alias

yeah，I just got it a few minute ago, thanks
